The low power consumption of this part in normal operation makes it ideally suited to portable, batter y-operated equipment. The AD5623R/AD5643R/AD5663R use a versatile, 3-wire serial interface that operates at clock rates up to 50 MHz, and they are compatible with standard SPI, QSPITM, MICROWIRETM, and DSP interface standards. The on-chip precision output amplifier enables rail-to-rail output swing to be achieved.
